Abstract

Novel indenylvinylidene iron complexes are formed in the reaction of alkynyl(η5-indenyl)iron complexes with phosphites and phosphanes in large excess by an intermolecular transfer of the indenyl ligand from iron to the Cβ atom of the alkynyl ligand; mechanistic studies indicate that the reaction proceeds by a radical pathway.
